Explain in detail:In estimating the actual resources of iron ore, economic and technical considerations, as well as the iron content of the rock, determine whether the deposit is classified as an Iron Ore or an "iron-bearing material".Hence the definition of the term 'Iron Ore' varies with time and place.

Explain in detail:Iron Ore Mining in Africa. The African countries in which iron ore production for export and local use is most prevalent are South Africa, Algeria and Mauritania. Morocco and Zimbabwe also produce ore, but only for local use. Many African countries have vast iron ore deposits that are not yet mined.

Explain in detail:Zimbabwe has huge iron ore deposits associated with banded ironstone formations in greenstone belts. Major deposits are estimated to be over 30 billion tonnes of reserves. Deposits with high-grade ore are found in Buchwa and Ripple Creek. Significant ironstone deposits include the huge Mwanesi deposit west of Chivhu and Nyuni near Masvingo.
Explain in detail:The Mwanesi mine is a large iron mine located in central Zimbabwe in the Midlands Province.Mwanesi represents one of the largest iron ore reserves in Zimbabwe and in the world having estimated reserves of 30 billion tonnes of ore grading 43% iron metal.. References
Explain in detail:Nov 12, 2019· Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
Explain in detail:Iron ore is rock which metallic iron can be extracted from. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust. This makes it one of the most abundant rock elements. Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron.
Explain in detail:While the first iron ore was likely meteoric iron, and hematite was far easier to smelt, in Africa, where the first evidence of iron metallurgy occurs, limonite is the most prevalent iron ore. Before smelting, as the ore was heated and the water driven off, more and more of the limonite was converted to hematite.
Explain in detail:Mining was Zimbabwe's leading industry in 2002, contributing 27% of export trade. The chief minerals were coal, gold, copper, nickel, tin, and clay, and Zimbabwe was a world leader in the production of lithium minerals, chrysotile asbestos, and ferrochromium, with more than half of the world's known chromium reserves.
Explain in detail:Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.
Explain in detail:Iron Ore 1.15 Zimbabwe has huge iron ore deposits associated with banded ironstone formations in greenstone belts. Major deposits are estimated to be over 30 billion tonnes of reserves. Some of the high-grade deposits are found at Buchwa and Ripple Creek, in the Midlands Province. Significant ironstone

Explain in detail:Properties. Chromite minerals are mainly found in mafic-ultramafic igneous intrusions and are also sometimes found in metamorphic rocks.The chromite minerals occur in layered formations that can be hundreds of kilometres long and a few meters thick. Chromite is also common in iron meteorites and form in association with silicates and troilite minerals. ...
